7 Claims. 1

This invention is directed to, and it is an object to provide, a novel combination window and Venetian blind; the window including an inner and outer pane mounted in spaced relation in a dust-proof casing, and the Venetian blind being mounted in said casing between the panes.

The combination provides a weather proof window especially desirable for air-conditioned homes, offices, etc., and in addition the Venetian blind is mounted in an attractive, out-of-theway position where it is not subject to dust accumulation and soiling, as are conventional, exposed Venetian blinds.

Another object of the invention is to provide a window and Venetian blind combination, as above, which includes novel mechanism for mounting and actuating the Venetian blind,

the blind actuating means being normally enclosed but accessible to the operator without in any way opening the window compartment in which the tiltable, and vertically adjustable, blind assembly is suspended.

An additional object of the invention is to provide a window and Venetian blind combination, asdescribed, which also includes a novel arrangement for the passage of ventilating air from the outside to the inside of the building independently of the assembly of the casing-supported panes and Venetian blind therebetween.

It is also an object to provide a combination window and Venetian blind which is relatively simple in structure, readily and economically manufactured, and easy to maintain when in use.

It is a further object of the invention to provide a practical and convenient combination window and Venetian blind, and one which will be exceedingly effective for the purpose for which it is designed.

These objects are accomplished by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings:

Fig. l is an outside elevation of the combination window and Venetian blind.

Fig. 2 is an enlarged fragmentary inside elevation, partly in section, of said combination Window and Venetian blind.

Fig. 3 is a fragmentary sectional plan view on line 33 of Fig. 2.

Fig. 4 is a fragmentary sectional elevation on line 44' of Fig. 2.

Fig. 5 is a fragmentary sectional elevation on line 55 of Fig. 2.

Fig. 6 isa fragmentary plan, mainly in section, of the detachable coupling at one end of the tilt rail.

Referring now more particularly to the characters of reference on the drawings, the combination window and Venetian blind comprises a rectangular casing, indicated generally at I, said casing being separated by an intermediate partition 2 into a relatively wide window compartment 3, and a relatively narrow vertical compartment 4 along one side of said window compartment.

The window compartment 3 is closed or defined by an outer, glass pane 5 and an inner, glass pane 6. The panes 5 and-6 are mortised into corresponding portions of the casing I, and

are retained in place by securing and sealing strips 1, whereby the window compartment 3 is weather and dust proof. The panes are flush with the walls.

The vertical compartment 4 is closed on the outside by a louvered panel 8 secured to the casing I and including a backing screen 9. On the inside, the vertical compartment 4 is normally closed by a vertically hinged door I0 adapted to open inwardly for access to said compartment 4.

The intermediate partition 2 is formed with a vertically spaced pair of ports II and I2. The

port II, which is normally closed by a removable plug I3, is provided for access from the vertical compartment 4 into the window compartment, as occasion may demand. The port I2 is for the purpose of ventilating the Window compartment 3 to prevent condensation on, or steaming of, the panes 5 and 6; this ventilating port I2 having a removable or replaceable filter pad I4 therein to prevent entry of dust into the window compartment 3.

A Venetian blind assembly, indicated generally at I5, is suspended in the window compartment 3, and is constructed and mounted as follows:

A pair of brackets I6 and I1 depend from the headboard I8 of the casin into the window compartment 3 in transversely spaced relation. A tilt rail I9 extends between the lower ends of the depending brackets I6 and I1, being supported at the left-hand end by an end pin 20 carried in a holding notch 2| in the bracket I6. At its opposite end the tilt rail 9 is supported by a detachable coupling, indicated generally at 22, from the adjacent end of an alined spindle 23 journaled in the lower end of the depending bracket I1 and extending through a bearing 24 in the intermediate partition 2.

The detachable coupling 22, as shown in detail in Fig. 6, comprises a compression spring 25 engaged between the bracket l7 and a floating end head 26 having projecting pins 2'! which seat in matching sockets 28 in the adjacent end of the tilt rail Hi. It is thus evident that the compression spring 25 normally urges the tilt rail I9 into frictional engagement with the depending brackets [6, whereby to maintain the blind assembly in adjusted position. The. detachable coupling 22 also facilitates initial installation, as Well as subsequent removal, of the tilt rail for repair or replacement of the blind assembly.

Suspension or ladder tapes 29 are secured to, and depend from, the tilt rail l9; such ladder tapes 29 tiltably supporting the blind slats 30 in the usual manner. 7 r

The raising and lowering control mechanism comprises a horizontal top shaft 3| journaled at one end in a bearing 32 on the depending bracket l6 and supported, at its opposite end, by'a detachable coupling 33 formed in part on the adjacent end of an alined spindle shaft 34 carried in a bearing 35 mounted in the partition 2. The detachable coupling 33 comprises a non-circular shank 33 on the horizontal top shaft 3| and a socket 3i on the spindle 34.

The detachable coupling 33 facilitates initial installation, as well as subsequent removal for replacement or repair, of the top shaft.

The horizontal, top shaft 3| carries a pairof transversely spaced spools 38 having lifting ribbons or tapes 39 running thereoff downwardly through slots 46 in the tilt rail [9, one side of said slots carrying a protective facing M to prevent undue wear on the corresponding lifting ribbon 39. The lifting ribbons 39 extend downwardly through slots 42 in the blind 33 and connected, at their lower ends, with the bottom rail 43.

It will be seen that with rotation of the spindle 23 and corresponding portion of the tilt rail 19, the angle of the slats 30 will be adjustable, while rotation of the spindle 34 and horizontal top shaft 3|, with the lifting ribbons 39 running on or off the spools 38, will cause raising or lowering of the blind.

The spindles 23 and 3d are adaptedto be rotated by the operator through the medium of sprockets 44 and 35 mounted on said spindles in the vertical compartment 4. and 45 are rotated by means of chains 48 and M running thereover and fitted at opposite ends with pull eyes 48, as shown. Thus, to adjust the blind either for tilt or vertically, the operator need only open the door It and then manipulate one or the other of the chains 46 or 4?. As is obvious, this can be accomplished without in any way gaining access into the window compartment 7 3, which remains dust-proof, with the Venetian blind assembly unsoiled in its position between the glass panes and 5;

When it is desired to obtain ventilation between the outside and inside of the building structure, the door 1 t is opened, whereby air may flow through the vertical compartment 4 between the louvered panel 3 and the then open door It). In this manner room ventilation can be accomplished without exposing the Venetian blind to.

H3 in port 12, assure against dust entry into the window compartment 3.

It should also be noted that the two-pane window, together with the relatively static air there-- Said sprockets 44 between, tends to limit heat exchange through the structure, which is valuable where the room is air conditioned.

If desired, a check valve and fitting can be substituted for filter l4, so that the dead air may be evacuated from the window compartment to further eliminate dust, dirt, and moisture.

From the foregoing description it will be readily seen that there has been produced such a device as substantially fulfills the objects of the invention, as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.
